I have a '07 Dodge 1 ton duelly with the 6.7 Cummins with the 6 speed auto tranny. I've never had a minutes worth of trouble out of it. I pull a Donzi 38ZR with it.

I want to put a performance kit in it to get more hp and more mileage. I don't want to modify my exhaust system if i don't have to. Can anyone save me the search time and tell me the best kit to get?

I can't wait til the Tickfaw 200 gets here.

I heard the SMARTY is good.

contact H & S performance 1 888 628 1730 your going to have trouble trying to get performance & mileage with that DPF & egr on there ,get rid of it and you will be extremely happy. that EGR is the internal engine contaminator, when I had 8000 miles on my 6.7 I pulled the horn above the grid heater and it was packed already with soot already ! these systems are what screw up the turbos also .43000 miles on mine now and th oil stays nice and clean between oil changes. watch your oil level rise after 1500 to 2500 miles on after an oil change, otherwise an excellent truck, pulls my fountain great ,set the cruise at 70 @ 1700 rpm and holds it great.Also ck out cummins forum.

in 07 there was 5.9's and 6.7's i have the smarty on my 6.7 because that is wat i had on my 5.9 but i have heard from freinds that the H&S is beter on the 6.7's than the smarty

Go to that link above and do your due diligence. I no longer have a diesel truck but I'm still a member there. The Cummins forum is the biggest and best website for Cummins owners.

Exactly, I don't understand the point of the egr systems with dpf and regen mode blah blah blah... causes more trouble and was absolutley pointless to add to all the big 3 hd's. Let's see worse fuel mileage...check, wasting fuel for regen...check, high egt's...check....whatever idiot came up with this for the epa I hope chokes on a chicken bone.

Funny how on all 3, once you remove the dpf and stop regen and have a good tune.. the trucks run much smoother, have way more power and torque, and get way better mileage and no worries of high egt's like before. What a bunch of putzs

2007 3500 6.7.....no trouble

Cummins is working on some inside-engine solutions. Hopefully they will be able to reduce emissions and soot without all the bandaid things they've put on the 6.7. My 5.9 had an EGR system inside the engine and the first time I turned it on after an oil change the oil was as black as it was before the change. Very frustrating.

Congrats to Dodge on the 2010+ dually fenders, they are great looking!

The Dodge is good looking and reasonably priced but the Made in Mexico sticker kills it!
